BENJAMIN F. FOSS, OF FAIRFIELD, MAINE.

RADIATOR.

Specincation of Letters Patent.

Patented Feb. 25, 190s.

Application filed April 22. 1907. Serial No. 369.642.

To all whom it may concern:

Be it known that I, BENJAMIN F. Foss, a citizen of the United States,residing at Fairfield, in the county of Somerset and State of Maine,have invented a new and useful Radiator, of which the following is aspecification.

rlhis invention relates to steam radiators', and more particularly tomeans whereby one or more portions of the radiator can be cut off fromthe steam supply so as to reduce the amount of heating surface andcorrespondingly reduce the temperature of the room to be heated.

Another object of the invention is to pro vide a simple and efficientform of valve which can be readily manipulated without danger of theparts becoming detached, all portions of the valve with the exception ofits stem being concealed within the radiator.

ith these and other objects in view the invention consists ofcertainnovel features of construction and combinations of parts whichwill be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a vertical longitudinal section throughthe lower portion of a steam radiator containing the presentimprovements, one of the valves yand its seat being shown in elevation;and Fig. 2 is an end view of one of the valves.

Referring to the figures by characters of reference, 1 designates asteam radiator made up of a plurality of communicating sections asordinarily and having an inlet 2 at one end while in the opposite endthereof is secured a tubular extension 3 interiorly screw threaded anddesigned to receive and to be engaged by a threaded stem 4. Suitablemeans, such as a hand wheel 5, is secured to the outer end of this stemto facilitate the rotation thereof and formed upon the inner end of thestem is a head 6. As shown in Fig. 1 the sections of the radiatorcommunicate near their lower ends through openings 7 in the usual mannerand the radiator is made up of three divisions each of which consists ofone or more radiator sections. The sections communicate only at theirlower ends and communication is established between the divisionsthrough eX- ternally screw threaded tubular members 8 which are insertedinto the openings 7 between the divisions.

For the purpose of convenience in describing the invention one divisionof sections has been designated by the character A while the otherdivisions have been designated by the characters B and C respectively.Within each of the tubular members 8 is iitted a tubular valve seat 9and these seats are oppositely disposed so that one of them projectsinto the division A while the other projects into division C.

The head 6 is mounted to rotate within a socket 10 from which extends ascrew threaded stem 11. A retaining rin 12 projects into the socket andserves to ho d the head in position therein. Stem 11 is engaged by acoupling sleeve 13 into which projects the threaded end of a spindle 14which extends through the tubular members 8 and has an intermediatethreaded portion 15 and a threaded end portion 16. Oppositely disposedvalves 17 and 18 are secured upon the respective threaded portions,valve 17 being located in section C while valve 18 is located in sectionA and the two valves being oppositely disposed. Each of the valves is inthe form of a disk having a circular groove 19 in which is disposed aring 20 of leather, rubber, or other suitable material, and said valvedisk is held against displacement upon the threaded portion of the stemby means of nuts 21 and 22. Each nut 22 has wings 23 radiating therefromand disposed to travel within the seat 9 and support the adjoining valvein proper relation to the seat.

As has heretofore been stated the valves 17 and 18 are oppositelydisposed. The distance between these valves is greater than the distancebetween the seats 9 so that by moving the spindle 14 in one directionboth of the valves can be unseated and steam will be free to pass fromthe inlet 2 through the two members 8 and into all of the radiatorsections.

Should it be desired-to reduce the heating surface of the radiator thestem 4 is rotated in one direction so as to cause it to feed inward. Thehead 6 will rotate in socket 10 and spindle 14 will be pushedlongitudinally without, however, rotating because of the contact of thevalves or their wings 23 with the members 8. Valve 17 will thus bepressed a ainst its seat 9 and the su ply of steam will be cut off fromdivision By rotating the stem 4 in the op osite direction its head 6will pull on the spindle 14 so as to unseat valve17 and seat valve 18.The two divisions B and C will therefore be cut off from the inlet 2 andonly the division A will be heated by the steam. By rotating'stem 4 soas to unseat the valve 18 without however seating valve 17 the steamwill be again free to pass into all the divisions ofthe radiator.

While the radiator has been described as sub-divided into groups it isto be understood that if preferred one section may constitute each groupand by the word group it is not my intention to necessarily restrictmyself to a plurality of sections.

It will be noted that a valve such as herein f v described permits theradiator to be easily form an intermediate and end divisions, one

of said end divisions having an inlet, and connected simultaneouslymovable valves disposed to alternately close, said valves being designedto establish or cut olil communication between the inlet division andeither or both the remaining divisions.

2. A radiator comprising a plurality of sections communicating solely atone end, said sections being arranged in an intermediate and enddivisions, one of said end divi sions having an inlet, valve seatsinterposed between the respective divisions, a s indle extending throughthe seats, oppositelly disposed va ves thereon, and means extending fromthe radiator for actuating the spindle to alternately close the valves,and establish communication between the inlet division and either orboth the remaining divisions.

3. A radiator comprising a plurality of sections having registeringopenings at one end through which they communieate,fvalve seats disposedin certain of the openings and sub-dividing the radiator into anintermediate and end divisions, one of said end divisions having aninlet, a spindle movable longitudinally through the seats, oppositelydisposed valves secured upon the spindle and within the end divisions,and means for alternately seating and unseating the valves.

In testimony that I claim the foregoing as my own, I have hereto aiiiXedmy signature in the presence of two witnesses.

BENJAMIN F. FOSS.
